In Toronto Mr. Xash found it in con-siderable numbers on spiraea, as many as a dozen being seen on one bush inAugust. This handsome insect cannot be classed amongst our noxiousspecies, as it rarely occurs in any numbers, being kept in check by its para-sitic enemies; the cocoons in winter are also attacked by woodpeckers, whoperforate the silken wrappings and suck out the liquid contents of thechrysalis. Amoncr other insects affectinsr the apple mav be mentioned the CommonEye-spotted Bud-moth {Tmetocera ocellana) which we always have with Apple Bucculatrix (B. pouiifoUella)—fig. 15—mining the leaves, was.

An unusual attack upon the foliage of Quince trees was reported byMr. Alister McKay, of Chatham. Large numbers of the leaves were foundto be riddled with roundish holes in September, and in October the singularflat oval cases containing the chrysalids were to be seen in numbers attachedto the leaves and to boards standine^ on end near the trees. The parent insectis a very beautiful minute moth called the Resplendent Shield-bearer(Aspidisca splcndorifcrella) which comes from the cocoons in May.
